AudioShare, the best audio management app for the iOS system in my opinion, got a great update with several new audio-related features like support for M4A ALAC (Apple Lossless) format AudioBus 3. If you need an app to work better with audio files like wav files, AudioShare is in my opinion the best solution for this. You can import/export quite easy audio files from your desktop computer and allows to manage perfectly all your individual wav files. With AudioBus support, you can even record your tracks straight to this audio app.
